Hi I am Portia,
I am the class representative of 5/6A for recreation.

Length: 16,987.2 km
Height: 2250 meters - 4.5 meters per level
Width: 16,987.2 km
Volume: approximately 649,171,169 km
Number of passengers: 7,079,000,000
Cargo: humans beings and food and water resorces
Landing system: all passengers evacuate into a smaller lighter escape pods, and they all have parachutes making the landing not so rough whereas the ark has a big parachute, the landing will be too rough for humans to survive, however it will not damage the ark to much
Materials used for main body: 2,300 flexible quilts of a silica-glass composite. The more sensitive belly of the shuttle is covered with 25,000 insulating tiles, each 6 in (15 cm) square and 5 in (12 cm) thick, made of a silica-borosilicate glass composite.
Materials used for heat shield: NASA's Orion Thermal Protection System
A desalination plant essentially separates saline water into two streams: one with a low concentration of dissolved salts (the fresh water stream) and the other containing the remaining dissolved salts (the concentrate or brine stream). The plant requires energy to operate and can use a number of different technologies for the separation of the saline water. The amount of the feed water discharged to waste in the brine stream varies from 20 to 70 percent of the feed flow, depending on the technology employed and the salt content of the feed water. Desalination is becoming more economically viable as the technology improves. Desalination plants can be provided in a wide range of outputs to cater for small isolated communities or to contribute substantially to water supplies for large cities and even for irrigation (Spain, United Arab Emirates). One of the processes for desalination is reverse osmosis (RO). It is a membrane separation process in which the water from a pressurized saline solution is separated from the dissolved material by flowing through a membrane. No heating is necessary for this separation. The major energy required for desalination is for pressurizing the feed water, typically up to 62 atmospheres for seawater. In principle, the saline feed water is pumped into a closed vessel where it is pressurized to overcome the osmotic pressure of the solution before diffusing through the membrane. As a portion of the water passes through the membrane, the remaining feed water increases in salt content. This portion of this feed water is then discharged without passing through the membrane.

reflection of my sessions so far:
I have had heaps of fun on Minecraft, it has been really interesting all of the different things you can create, so far I have created many recreational thing, such as:
A garden, a tennis court, a marine park and a water fall
all of these things have been surprisingly easy to make once you get the hang of it. Next session I am going to start to make some more complex things such as stadiums, I will also begin to fence o some areas for national parks, and make some signs. Next time we get together with the level I will allocate things to do and make for each class. That way we won't have for example several stadiums and no parks.
6th of December:
In this session I began to fence of an area for a national park, another member in my district also had a great idea to make a bike path with a cafe on the side with a window enabling bikers to either quickly have a coffee or sit down inside.
